Specification of Letters Patent,

Patented Dec. 24, 1907.

Application filed June 14, 1907. Serial No. 378,963.

To all whom it may concern;

Beit known that I, HENRY P. DECKERT, a citizen of the United States,residing at Marion Junction, in the county of Turner, State of SouthDakota, have invented certain new and useful Improvements in Wrenches;and Ido hereby declare'the following to bea full, clear, and exactdescrip- 'tion of the invention, such as will enable others skilled inthe art to-which it appertains to make and use the same.

This invention relates to ratchet wrenches and has for its object torovide a wrench of this character which will e applicable to anyordinary size of nut.

In order that the wrench may be adjusted I as above stated, I haveformed through the head of the Wrench an elongated nut receivmg opening,and adjustable in this opening by reason of its swivel connection with aset screw, is a plate which cooperates with one end wall and with'theside walls of the opening to embrace the nut.

In the accompanying drawings, Figure 1 is a side elevation of a wrenchconstructed in accordance with my invention, Fig. 2 is a bottom planview thereof, Fig. 3 is a vertical longitudinalsectional viewlongitudinal sectional view through the head and a portion of the handleof the wrench, Fig. 4 is a detail horizontal sectional view takenthroughthe head and a portion of the handle andshowing the ratchetmechanism of the wrench, and, Fig. 5 is a detail perspective View of theplate and the set screw connected therewith. Fig. 6 is a detail verticalthrough the sleeve.

As shown in the drawings the wrench comprises a head 6 which issubstantially cylindrical inform and includes a reduced portion 7 withwhich latter is rotatably en'- ga'ged a two-part collar portion 8,formed integral with one end of the handle'9 of the wrench, there beingan annular rack element 10 received between the two members of thecollar portion 8. Cooperating with this rack element 10 is a pawl devicewhich will be presently more specifically described.

Formed through the head 6 and opening through the ends thereof is anelongated opening 11 and engagedthrough ofie'side of the said head 6 andextendinginto the said opening, through one end wall thereof, is a setscrew 12 to the outer end of which is,

swiveled a plate 13, which plate is substantially rectangular'm form andisof such width that its sideedges abut'the side walls of the opening11. opposes that end wall of the opening other than the one, throughwhich the set screw 12 is engagedand the said plate cooperates with thesaid end wall and with the side walls of the opening, to form a nutreceiving opening, it being understood that the plate 13 is adjustable,to and from the said end wall, by turning the set screw 12'and thatconsequently a nut of' any ordinary size may be receivedin the nutreceiving opening. In order that the plate 13 may .be guided in theopeningl'l, grooves 12 are formed in the side walls of the opening andlugs 13 are formed at the side edges of the plate 13 and work in thegrooves.

That portion of the handle 9 of the wrench with whichv the collarportions 7 are formed integral, is bifurcated as at 142 and, pivoted inthe bifurcation are pawls 15, the pivots for the pawls being indicatedby the numerai 16. Each of these pawls includes a toothed orworkingportion 17 which cooperates with the annular rack element 10 ofthe wrench.

' at one side thereof, the pawls being held in such engagement by meansof springs 18 which seat at one of their ends in sockets 19 formed inthe vertical wall of the bifurcation 14 and at their opposite ends seatin similar sockets formed in lugs 20, formed integral with respect tothe awls. These lugs 20'project outwardly of t e bifurcation andhave'their-forward sides rounded as at 21.

In order that the pawls may be independently brought into engagementwith the ratchet.10,- a sleeve 22. is engaged upon the handle of thewrench directly rearwardlyof the two-part collar portion, the sleevebeing adapted for rotation upon the handle but being limited in itsmovement, by a. in 23 -which is removably fixed in the hand e and whichworks in a recess or cut-away ortion 24 formed at the inner end of the seeve it being understood that the formation'of this recess results inshoulders 25 which abut One face of the plate 13 I against thes aid pin23 when the sleeve is at either limit of its rotary movement. 'Inteeriorly the sleeve is providedwithacontinuous annular groove- 26. Theinterior wall of the sleeve is also recessed at diametrically oppositepoints as .at 27 so that the sleeve may be slip ed overthehandle and theheads 20 oft e pawls be permitted to pass, by way of the recesseshitothe groove 26.

This grooveis contracted'as at 28 at one siderides over one or the otherof the pawl heads 20 when the sleeve is rotated to move one or the otherof the pawls out of engagement with the ratchet 10. c

What is claimed, is-

A wrench of the class described comprising a head, 'a handle, the headbeing reduced for substantially one-half its length and provided with anut receiving opening in its unreduced end, a two part collar portionformed integral with one end of the handle and receiving the reduced"portion of the head, an annular ratchet fixed upon the reduced portionof the head between the collars of the said collar portion, the handlebeing bifurcated at that end at which the two-part collar portion isformed, pawls pivoted in the bifurcation and ada ted to co-.

operate independently with t e ratchet, springs tending to'hold the'pawls in such'engagement, a lug formed integral with each of the awls,and a sleeve rotatably fixed upon the handle and inclosing the saidbifurcated portion thereof, the sleeve being provided 'interiorly withan annular groove which is contracted to form a cam portion which is adated to ride over one or the other of the praw lugs to move thecorresponding pawl oni engagement with the ratchet.

In testimony whereof, I aifix my signature in presence of two witnesses.

HENRY P. DECKERT.
